Anyone out there using the KF7P standoffs or similar and raising/lowering your tower successfully without observation? Anyone out there using the KF7P standoffs or similar and have had snagging probl
Concrete cures, not dries. As stated in prev posts minimal water in a stiff mix is harder to work but cures to a stronger final strength. Left to their own discretion often times concrete contractors
Do be careful if DIY cement work. I just did 26 bags of 60 lb each to stand up a pipe. It is pretty hard work. My small electric mixer can just do 3 bags at a time (barely) Pipe has been vertical for
Too bad the angle of the dangle is all wrong for Danforth style anchors. I 'dig' all my screw anchors in. Dig a hole to the proper depth, slit the tower side of the hole for the shaft, and place the
Some bird repellent methods: 1. Tanglefoot. It is a sticky non-corrosive goo you put where birds roost/perch and they HATE IT. It is non-toxic but birds and other critters hate it. 2. Ultrasound. Ult
Mike, Different freqs for different varmints. I like the the ultrasonic yelper function on my repellers that comes on and off in a pseudo random manner. Birds don't like it. They will get used to nea
Larry, I have problems with swallows. When they perch on the ceiling fan blades on the back porch I blip the off-on switch with increasing duty cycle until they can't hold on due to G forces and are
I have a Hy-Gain Hy-Tower on top of an all metal barn. Base is about 23 ft AGL. I have no radials. It works pretty well. I got a recommendation to put at least 4 radials on the roof (2.5:12 pitch gab
Yes, Grant... Very interesting problem. My building has 10 steel columns, 4 at the corners and 3 along each long wall with one centered and the others equally spaced. These are Ufer grounds, more or
"I don't know of a practical center feed for a vertical dipole that does not include a serious common mode choke at the feedpoint." What about a coaxial dipole? 73 Patrick AF5CK I noted the "simple"
Roger, Your UV is not nearly the intensity of the 5000 ft high desert QTH. What works for you will not work with the intense UV of the high desert. Ray, I think the dripline is something to consider.
Larry, the canvas is a good idea and it can be painted as well to extend its life. Good UV resistant house paint will do the job. I have seen old used canvas hose used to protect cables. I remember t
Larry, It is basically an intensity and exposure time issue. I sunburn easily. I can attest to getting a sunburned forehead while wearing a big brimmed hat while fishing. The reflected UV can be quit
Are you suggesting the liquid tight for a covering on the cables going to the antenna on a crank-up tower? Flexible conduit which is both outdoor and UV rated is used in the electrical industry. One
Mike (and anyone else if interested) I may have forgotten to mention that any highly repetitive sound will condition the birds and lose effectiveness over time. Random or pseudo random sequencing is
Has anyone experience to share regarding a tuner remoted to the tower? I have used a few manually adjusted tuners and in the marine industry automatic tuners that typically were programmed for discre
I have used a mast head mounted shunt fed 1/2 wave marine band antenna (Metz) on our sailboat interchangeably (1X2 coax switch) between my 2M and marine band VHF rigs. At a height of 50 ft or so it w
I'm aware of all the things you mention and more. I think the light bulb comment is unwarranted. You will note although my info is anecdotal it nevertheless represents over 20 years of hands on exper
Absolutely no offense taken. I read with interest and appreciate your contributions to the technical issues on this site. I am just standing up for a solution that was good enough and proven to be so
